Impact of Repeated Point Prevalence Surveys on Pediatric Antimicrobial Prescribing during the TeleKasper Study
In the TeleKasper study involving 33 German pediatric hospitals, repeated point prevalence surveys were independently associated with significant improvements in the quality of antimicrobial prescribing, whereas the multimodal stewardship intervention itself showed no independent effect.

In hospitals around the world, doctors frequently prescribe antibiotics to treat children with infections. While these medicines are life-saving, they are not without risk. When used too often or incorrectly, bacteria can learn to survive them, a phenomenon known as antimicrobial resistance. This growing threat means that common infections could one day become untreatable. To prevent this, medical teams strive for "antimicrobial stewardship," a careful approach that ensures the right drug is given to the right patient at the right dose, and only when truly necessary. A common way to check how well hospitals are doing this is through a "point prevalence survey." Imagine a team of experts walking through a hospital on a single day, looking at every child currently receiving antibiotics to see if the treatment matches the best medical guidelines. For years, these surveys have served as a mirror, showing hospitals their mistakes. But a lingering question remained: does simply looking in the mirror change how people behave, or is the mirror just for observation?
A large study conducted across Germany sought to answer this question by turning the mirror into a tool for active improvement. Researchers from the TeleKasper project worked with thirty-three non-university children's hospitals, a group that often lacks immediate access to specialized infectious disease experts. They set up a system where these hospitals received regular, quarterly surveys of their antibiotic use. Crucially, this was not a one-time check. The surveys happened ten times over two years. After each survey, a panel of experts reviewed the cases and provided specific feedback to the doctors, pointing out where treatments could be improved. This process was part of a broader effort that included telemedicine consultations and educational resources, but the researchers wanted to know if the repeated act of surveying and giving feedback was the engine driving change, or if the other tools were doing the heavy lifting.
The study followed more than eight hundred children who were being treated for active infections. The researchers defined "optimal care" as a situation where a child had a clear reason for taking antibiotics, was given the recommended first-choice drug, and received the correct dosage based on their weight. When the team analyzed the data, they found a surprising result. The introduction of the broader telemedicine program itself did not immediately cause a jump in the quality of care. The hospitals that had just started the new program were not significantly better than those that had not yet begun. Instead, the improvement came steadily and consistently with every single survey that was conducted.
With each new survey, the odds of a child receiving optimal care increased. By the time the study reached its final surveys, the proportion of children receiving perfect care had more than doubled, rising from about twenty-six percent at the start to fifty-three percent at the end. This improvement happened regardless of whether a hospital was in the early stages of the program or had been participating for a long time. Even the hospitals that were waiting to start the full intervention saw their prescribing habits improve simply because they were participating in the surveys and receiving feedback. The researchers noted that the use of certain broad-spectrum antibiotics, specifically cephalosporins, dropped significantly, and doctors became better at documenting how long a treatment should last.
The findings suggest that the act of repeatedly measuring performance and sharing the results with the medical team is a powerful force in itself. It appears that when doctors know their prescribing habits are being reviewed and discussed, they become more attentive to the guidelines. This effect, often called the "Hawthorne effect" in social science, describes how people modify their behavior when they know they are being observed. In this case, the observation was not passive; it was paired with expert feedback that helped doctors understand their specific errors. The study indicates that these repeated surveys are not just a way to count mistakes, but a method that actively teaches and corrects behavior over time. While the researchers caution that long-term sustainability after the study ends remains to be seen, the data clearly shows that a cycle of regular checking and constructive feedback can significantly improve how antibiotics are prescribed for children, offering a practical path forward in the fight against drug-resistant bacteria.
